About B1210

B1210 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1210 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1210 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Electronic Integrated Cluster (EIC) module monitors a network of instrument cluster switches that handle driver interface functions such as trip reset, display mode selection, and vehicle information readouts. DTC B1210 is set when the EIC module detects an open circuit condition on the Switch 2 input, meaning the expected voltage transition is not observed when the switch is actuated or the pull up reference is lost at the input pin. Most EIC switch inputs operate as a momentary contact pulling the signal line to ground or a reference voltage, with the module interpreting the state change...
